googol-Choo-Choo 3D is a 3D model railroad simulation program. It is easy to make your own layout by dragging and dropping track items, or other items, on your layout. You can see the layout in 3D from driver's seat of a running train or from several other locations. If you want to create your own trains or structures, you can do it with 3D modeling software and import the file into googol-Choo-Choo 3D.
